动词不定式的句法功能
1)主语:
例1. To finish the work in ten minutes is very hard.
例2. To lose your heart means failure.
★ 动词不定式短语作主语时,常用it作形式主语,例如上面两句可用如下形式:
It is very hard to finish the work in ten minutes.
It means failure to lose your heart.
2)表语:
例1. Her job is to clean the hall.
例2. He appears to have caught a cold.
3)宾语:
下列动词只能接不定式作(直接)宾语:
hope, wish, want, ask, help, refuse, learn, demand, care, choose, arrange, expect, decide, agree, plan, promise, offer, manage, pretend, prepare, elect, fail, long, determine, desire等。
不定式一般不做介词的宾语,但是可以放在介词but/except之后做宾语。
如果介词之前有行为动词do的各种形式,那么这些介词后的不定式不带to;否则就要带to。即所谓的“前有do后无to”。
例1. I have no choice but to stay here.
例2. I can do nothing but stay here.
it作形式宾语
如果不定式(宾语)后面有宾语补足语,则用it作形式宾语,真正的宾语(不定式)后置,常用的动词有(consider, think, make, find, believe, count, declare, fancy, feel, guess, imagine, judge, prove, see, show, suppose, understand, take等)。
注:这里高考常考的动词有:consider, make, find, feel, see, suppose, take 等。
例1. We consider it our duty to support good leaders.
例2. The new method makes it possible to complete the task faster.
4)作宾语补足语:
下列动词之后用省略to的不定式作宾语补足语,用一句口诀来记忆:
“五看三使两听一感觉”
see, look at, watch, notice, observe/ make, let, have/ listen to, hear/ feel
5)定语:
下列情况下一般用动词不定式做后置定语:
★不定式表将来
I have a meeting to attend this afternoon.
★用来修饰被序数词、最高级限定的中心词。
She was the first woman to win the gold medal in the Olympic Games.
The best way to earn respect was to study hard and achieve high grades.
★用于修饰的词是抽象名词时,常见的有:ability, chance, idea, fact, excuse, promise, answer, reply, attempt, belief, way, reason, moment, time等,这些名词经常被no,
